Welcome jaymac.

As for public land, the key is to do some pre-season scouting.
Get some maps, a compass and if possible (not necessary but
kind'a helpful) an inexpensive GPS unit. Use the maps to locate
some likely spots AWAY FROM THE ROADS AND WELL TRAVELED
PATHS. This is key on public land. Most will tell you (because
it's true) the average human will not walk very far into the woods.
This will be an advantage to you. Get to know the area you want
to hunt. I'm not much for tree stands myself as I like to be mobil.
Conditions change.
If you have access to some good private land I'd say try to stay
on. If you're worried about wearing out your welcome find some
way to be useful to the owner. Volunteer to do some work, give
them some type of gifts or just be a good steward. Don't give
up a hunting spot.

Good luck and have a great season.
God bless,
PK
